' SCREEN rAsTnNER'ANnrRo'rEcTo Application filed A pri19,

My invention relates to' window screen,

fasteners and protectors, audit consists in the combinations, constructions and arrangements herein described and claimed. v

An object of the invention is to provide a simple, inexpensive and highlyeflicient device for holding an extensible window screen locked in. applied position in a window frame.

A further object of the invention is to provide a device of the character described which is adapted to look a window screen to the frame of a window in-which the screen is placed so that'the screen cannot be -removed intact, from the outer side ofthe window, thus preventing an iinauthorized"person from'gaining entrance to the interior of a building in which the-windowis pro vided by removing the screen from the win;

1 1 thereof broken I away and other portions I H I I mjay bean extensible window screen of ordow without breaking the screen. I a v A still further object of the invention is 'to provide a device of the character deing screens of various widths within 'a' considerable range of sizes'in window frames.

Other Ob ects and advantages Will be aparent from the followin descrintion considered in conjunction with the accompanying drawings, in which Figure l is a view showing a fastener and protector'embodying the invention in"posi, tion to look a window screen in'position in a window frame, the fastener and'iprotector being shown inplan and the window frame and screen being shown in-horizontal secy j 7 Figure 2 is a relativelyenlarged plan view; of the fastener and protector with portions shown in section. 7 1 Adevice embodyingthe invention as illustrated in F igur es l and 2 has an elongated body extensible in length and comprising a 'tiibular section 1 open at one end for the reception of an end of asecond section 2 of the body. Thesections l and 2 are in slid ing' engagementso that-the length .of the The sections 1 and2 and the 6gand 7 may be made of :any suitable mate 1924". Serial is. 705,276.

The-locking pin 6 be integral with-the section 2 or may be a'separate element rigidly secured to the section 2in any suitable known manner. :The

section '1 is provided with a locking pin 7' 7 which extends from the marginal portion of tlie outer endofthe section 1 so that the pins 6 and 7 may be arranged in axial align- I ment with each otherby securing the sections 1 and 2 together and to trated in Figure 2; v

rial and any desirable size.

r-ious parts of the device, the operation thereof'may be read-ily understood. The device is designed tofibe positioneddnwardly of. the screen material: of i a'- window screen which may be of ordinary rigid construction or d inary construction;as indicated at 9 in Fig ure 1. The. greatest application of -the deg pin 7; will be securely locking pins v From the foreo'cing description of 'the va improperly into a dwelling house than the usual rigid window screens which are more permanently secured to the window frames. An extensible window screen ordinarily is placed within a window frame, such as that indicated at 10 in Figure 1 with the side bars of the window frame received in the guideways which are defined by adjacent vertical guide strips 11 in conjunction with the window jambs 12 to which said strips are secured. In order to remove the window screen from the window frame, it is only necessary to collapse the window screen or in other words to slide the sections thereof in respect to each other until the side menr bers of the window screen frame have been moved inwardly beyond the inner edges of the guide strips 11. As. is ell known, win-. dow screens of the extensible type of con struction frequentlyare displaced from window frames because of accidental collapse thereof and many accidents occur because of objects and persons, principally small children, falling from a window from which the window screen was displaced when. the weight of the object or person was imposed against the inner side of the screen. Of course, the frame of an extensible screen could be secured by nails to the window frame but this is objectionable since convenient and facile removal and replacement of the window screen to permit lowering and raising of the window sashes when desired or for any other cause would be precluded and moreover the securing of the screen frame to the window frame by means of nails or like fastening elements would tend to mar and damage the window frame.

lVhen a fastener and protector embodying theinvention and as illustrated in Figures 1 and '2' is employed, horizontally aligned openings 13 are formed through the side members of the indow screen frame and sockets or openings 14 are formed in the window jambs in position to register with the openings 13 when the window screen is in applied position in the window frame, as shown in Figure 1. The openings 131t are adapted for the reception of the locking pins at the opposite ends of the body of the device. The locking pin at one end of the body of the device is inserted through one of the openings 18 into the associated opening or socket 14 until. the adjacent end of the body of the device is in abutting relation to the inner face of one of the side members of the screen frame.

The body of the device then is adjusted in length until the locking pin at the other end of the body is extended through the other opening 18 into the opening or socket 1st at the other side of the window to posi.-

tion the second end of the body of the device in abutting relation to the outer face of the ad acent side member of the screen frame.

members of the screen frame and the end walls of such sections of the device thus serve as stop shoulders or walls and the locking pins not only are braced because of the engagement of the ends of the body of the device with the side members of the screen fame but no undue pressure is placed on the inner ends or bottom of the sockets 14.

The sections 1 and 2 of the body of the device are lockedto each other through the use of a set or thumb screw t when thebody or the device has been adjusted in length as desired to effect the locking of an extensible screen in a window frame of a given width, The window screen thus will be securely held against collapse and against accidental displacement from the window frame. Also, it will be manifest that the screen frame cannot be displaced by any person from the outside of the window unless the window screen is broken or damaged to an extent necessary to permit manipulation of the thumb or set screw of the device by the person at the outer side of the window.

Obviously, my invention is susceptible of embodiment in forms other than those illus trated in the accompanying drawings, and I therefore consider as my own all modifications and adaptations of the forms of the device herein described as fairly fall within the scope of the appended claims.

I claim 1. A devicefor holding an extensible window screen against collapse from applied positionin' the window frame, comprising a body extensibleto vary the length thereof and provided with reduced pin extensions at the outer ends thereof for insertion through aligned openings in the side members of the screen frame into openings in the side members of the window frame, said pin extensions extending in the direction of length of said body in eccentric relation to the body.

2. A device of the character described, a tubular sect-ion open at one end, a rod like section slidably received at one end in the bore of the tubular section, a collar carried by the tubular section in engagement with the open end thereof, a securing screw threaded through aligned openings in said collar and said tubular section for engagement with the inserted portion of said rodlike section to lock said sections together, and pin-extensions at the outer ends of said sections, said pin extensions being of less area in cross section than the adjacent. portions of the sections of said body and extending from the marginal portions of the outer ends of the sections, in tion to said sections. V

3. A device of the character described, a tubular section open at one. end, a rod like section slidably received at one end in the bore of thetubular section, a collar carried by the tubular section in engagement with the open end thereof, a securing screw threaded through aligned openings in said I collar and said tubular section for engagement with the inserted portion of saidrodeccentric re1alike section to lock said, sections together,

and pin extensions at the outer. ends of said j sections, said pin extensions being of -1ess tion to the sections, said rod-like section be-' ing enlarged adjacent to its outer end to 15 I area in' cross section than the adjacent porcorrespond inhcross sectional area and contour to said tubular section.
